Autzoo.1064 hacknews utzoo!henry Tue Oct 27 17:51:12 1981 crash yesterday The cause of yesterday's crash is not known with certainty. It appears the system hung up somehow internally: there were plenty of processes ready to run swapped out, but none in core, and the swapper and the disk driver (roughly speaking) disagree on whether there was a swap in progress. And the system can't run processes if they aren't in core.
